F3 Hits 2.0m of 31.4% U3O8 Within 7.6% Over

12.0m at JR

Kelowna, British Columbia--(Newsfile Corp. - June 12, 2024) -

F3 Uranium Corp

(

TSXV: FUU

)

(

OTCQB: FUUFF

) ("

F3

" or "

the Company

") is pleased to announce assay results for fifteen drillholes

from the winter 2024 drill program, including PLN24-116 which was cored in the JR Zone (see NR

January 30, 2024) and which returned

12.0m of 7.6% U

, including a

The ongoing

summer exploration drilling around the southern end of A1 and northern end of B1 continues to yield

excellent structure with intermittent anomalous radioactivity, with PLN24-152 intercepting two distinct

radioactive intercepts with up to 760 cps.

Exploration is proceeding with two diamond drills, one focused on systematically testing the A1 shear

using short holes, infilling along strike in areas with low drillhole density and intercepting intermittent

weak radioactivity. The second diamond drill is currently focusing on the area between the southern end

of the A1 shear and the B1 shear, an area of structural complexity marked by the cross-cutting Harrison

fault, with related A1 shear splays interpreted as fault horses on the footwall side of the Harrison fault. Of

particular interest is PLN24-152 (see Photo 1) which intersected two radioactive intervals within

graphitic and clay altered shear zones including the main A1 shear.

A large-scale ground gravity survey, including coverage over the A1 and B1 shears is still in progress.

Sam Hartmann, Vice President Exploration, commented:

"We are very pleased with the results of the ongoing exploration program, in particular the area around

the southern end of A1 where our geological targeting model is improving. The area between the A1 and

B1 shears continues to be rich with the right kind of structures - altered and displaying radioactivity. Our

release today includes winter assays up to hole PLN24-131, with an additional fourteen holes still

outstanding, including six from B1. Strongly anomalous exploration geochemistry results at B1 with up to

0.022 % U

O

in PLN24-122 reinforce our belief that the area has the potential to host high grade

uranium. This is bolstered by the concurrent release of scintillometer data including PLN24-152, which

intersected two radioactive intervals - coupled with very favorable structure and alteration."

Handheld spectrometer composite parameters:

1: Minimum Thickness of 0.5m

2: CPS Cut-Off of 300 counts per second

3: Maximum Internal Dilution of 2.

0m

Natural gamma radiation in the drill core that is reported in this news release was measured in counts

per second (cps) using a handheld Radiation Solutions RS-125 scintillometer. The Company considers

greater than 300 cps on the handheld spectrometer as anomalous, >10,000 cps as high grade and

greater than 65,535 cps as off-scale. The reader is cautioned that scintillometer readings are not directly

or uniformly related to uranium grades of the rock sample measured and should be used only as a

preliminary indication of the presence of radioactive materials.

Composited weight % U3O8 mineralized intervals are summarized in Table 1. Samples from the drill

core are split into half sections on site. Where possible, samples are standardized at 0.5m down-hole

intervals. One-half of the split sample is sent to SRC Geoanalytical Laboratories (an SCC ISO/IEC

17025: 2005 Accredited Facility) in Saskatoon, SK while the other half remains on site for reference.

Analysis includes a 63 element suite including boron by ICP-OES, uranium by ICP-MS and gold analysis

by ICP-OES and/or AAS.

The Company considers uranium mineralization with assay results of greater than 1.0 weight % U

3

O

8

as

"high grade" and results greater than 20.0 weight % U

3

O

8

as "ultra-high grade".

All depth measurements reported are down-hole and true thickness are yet to be determined.
